The legal technology industry is experiencing a transformative period, marked by a surge in artificial intelligence integrations and strategic partnerships. A recent legal tech rundown highlights key developments, including a significant collaboration between Thomson Reuters and DeepJudge, alongside Workday’s introduction of a custom AI model library.
Thomson Reuters and DeepJudge Forge AI Partnership
On October 22, 2025, Thomson Reuters, a global leader in content-driven technology, announced a new partnership with DeepJudge, an AI innovator specializing in knowledge retrieval for law firms. This collaboration aims to integrate DeepJudge’s AI-powered enterprise search capabilities into Thomson Reuters’ CoCounsel Legal offering. The objective is to provide law firms and legal departments with secure, permissioned access to internal data at scale, effectively unifying a firm’s proprietary knowledge with Thomson Reuters’ extensive content library.
DeepJudge, founded by former Google AI researchers, has been recognized for its ability to instantly surface insights across internal knowledge bases with exceptional relevance and speed. Raghu Ramanathan, President of Legal Professionals at Thomson Reuters, emphasized the strategic importance of this partnership, stating, ‘DeepJudge brings breakthrough contextual enterprise search that unleashes the full power of a firm’s internal intelligence.’ This move is part of Thomson Reuters’ broader mission to build robust AI infrastructure for professional work, combining cutting-edge AI with professional-grade governance, content, and reach.
Workday Introduces Custom AI Model Library
In parallel with these developments, Workday has launched a custom AI model library. While specific details of this launch were not extensively covered in the broader legal tech roundup, its inclusion underscores a growing trend among enterprise software providers to offer tailored AI solutions that can be adapted to specific organizational needs, including those within the legal sector. This initiative by Workday is expected to empower businesses to deploy AI more effectively across various functions, enhancing efficiency and decision-making.
Broader AI Impact and Investment in Legal Tech
The legal tech sector’s embrace of AI extends beyond these partnerships. Thomson Reuters, for instance, is investing over $200 million annually in AI development. Recent innovations from the company include the beta launch of ‘Deep Research’ on Practical Law, which expands its agentic capabilities and deepens integration with trusted Thomson Reuters content. This feature, along with CoCounsel Deep Research on Westlaw, is slated for availability in the U.S. and UK in the first half of 2026. Furthermore, CoCounsel is expanding its regional availability, with French, German, and Japanese versions becoming accessible to customers in October.
The impact of AI on legal professionals is becoming increasingly evident. Research indicates that UK legal professionals anticipate AI will save them approximately three hours per week, translating to an average annual value of over £12,000 per lawyer and an estimated £2 billion impact across the UK legal industry.
Other notable AI-related news in the legal tech space includes discussions around Italy’s new AI law and its implications for European developers, ongoing legal challenges against AI developers like OpenAI and Apple concerning data usage and safety, and the release of new Gen AI-powered platforms for patent management. A benchmark study by Vals AI even suggests that both legal-specific and general large language models are now capable of performing legal research tasks with accuracy comparable to or exceeding that of human lawyers.
